Ureteroscopy With High-powered Holmium:Yag Laser Lithotripsy With and Moses On or Moses Off
Sponsor: Northwestern University
Summary
The purpose of this study is to compare Moses 2.0 pulse modulation technology and the standard high powered Holmium Laser lithotripsy and how it will affect time in the operating room, time using the laser, laser energy, and stone free rates. Currently Moses 2.0 laser technology is FDA approved and currently used in practice since 2021. No study to this date has compared Moses 2.0 without pulse modulation laser technology to Moses 2.0 with pulse modulation laser technology. The study will be including kidney and ureteral stones (a kidney stone located in the tube between the kidney and the bladder) that are 6mm and greater, but less than 20 mm in size undergoing ureteroscopic treatment. High powered lasers are used for "dusting". Dusting is when a laser is used to break a stone down into tiny fragments that are able to pass through the urine.
